 Presentation Notes

The Dulles Silver Line Phase II (DSP2) is an 11.4 mile extension of the Washington Area Metro Transit Authority’s Silver line. The three miles of elevated guideway lies within the Culpeper Fault Basin, a geologic feature within the Piedmont Region that was formed during the Triassic Geologic Age.  


Very large lateral loads are produced along the guideway by transit braking, rail temperature, and centrifugal forces on curves. These lateral loads produce large moments at the foundation level due to the height of the guideway. An evaluation of various foundation systems was performed and mono-drilled shafts, socketed into rock, were selected to provide the most economical support of the aerial guideway. Vertical loads are resisted by side friction and end bearing in the rock socket, while moments and lateral loads are resisted by the stiffness of the shaft and the rock socket. The large lateral loads and moments produce very large shear forces in the shafts at the rock interface.  

A load testing program consisting of, three O-cell axial load tests and three lateral load tests were performed on test shafts instrumented with strain gauges, extensometers, and inclinometers. The challenge in developing the load testing program was how to reproduce the effects of the extremely high design loads along the test shafts, considering the practical limitations of the load test equipment. The process of developing and executing the load tests, and analyzing the test results will be discussed.

Bill Billiet, P.E., is an Associate Engineer with Schnabel Engineering.

 Presentation Notes

A Tale of Two Stabilizations

Collectively, these two case histories illustrate how the specific conditions of a particular slope or landslide stabilization project necessitate creative approaches to a design and construction solution in addition to the value of a collaborative problem solving approach between engineer and contractor.

 Old Croton Trailway Stabilization

 In March 2015, a 185 year old gravity stone retaining wall supporting a 50 foot slope failed, resulting in a landslide of approximately 500 cubic yards of fill, glacial till, boulders, and deleterious materials. The landslide debris collided with an 8-story, 100-unit apartment building and exposed the historic (inactive) Croton Aqueduct. The building was immediately evacuated and temporary stabilization was provided by the local fire department. The New York Office of General Services invited Moretrench American Corp. to work on the emergency design-build team to stabilize the slope, protect the buildings above and below the slope, and rebuild the wall.

 Stabilization of S.R. 38 Emlenton Hill Improvements

As part of the reconstruction of S.R. 0038, Section A00, a roadway fill was constructed to accommodate realignment of S.R. 0038 between the I-80 Exit 42 interchange and the S.R. 0268 intersection near the bridge over the Allegheny River into Emlenton Borough. Structural retaining walls were constructed to support the realigned roadway along the steeply sloped hillside. The tallest of these walls consists of a tied-back soldier pile retaining wall requiring embedment into rock. Finite element models were created for each design height to analyze construction staging for the unique bottom up construction.

 This project case history discusses the intricacies of the wall design along with some of the challenges associated with its location along the steeply sloped hillside and includes the construction process, specialty equipment and unique procedures which were required to install the soldier piles, steel wales and the rock anchors using bottom-up construction methods.

 Speaker Biography:

Mr. Bennett has been involved in the design and management of specialty geotechnical construction projects throughout the Mid Atlantic United States for over 20 years. He specializes in the design and analysis of deep foundations, ground anchors and anchored structures primarily focusing on tieback walls, soil nailing, micropiles, drilled shafts, augercast piles, foundation underpinning, tiedowns and grouting for structural support. Mr. Bennett earned his BS and MS degrees in civil engineering, specializing in structures and soil mechanics, from West Virginia Institute of Technology and has completed a Master of Engineering and Technology Management degree from George Washington University. He is a registered Professional Engineer, an active member of ADSC, ASCE and DFI, and sits on a number of industry technical committees including the ADSC/DFI Micropile Committee (Immediate Past Co-Chairman), the ASCE Geo-Institute Earth Retention Systems Committee , and DFI Tiebacks and Soil Nailing Committee (Past Chairman).

Mr. Bennett serves as Business Development Manager for Moretrench American Corporation in the Mid-Atlantic and Midwest regions of the United States.

Presentation Notes:

During a record rainfall on April 30, 2014, a century-old, stone retaining wall between a dense urban roadway (26th Street) and the CSX Transportation (CSXT) railroad track in Baltimore, MD failed. The failure sent part of the roadway, along with tons of soil, boulders, light poles, and eight parked cars, nearly 40 feet down, obstructing the tracks and halting rail traffic on the busy railway providing service between the Port of Baltimore and points north. Fortunately, no one was injured. The failure forced the evacuation of 19 homes until the first phase of earth-retention construction was complete. Due to the time sensitivity of the temporary retaining wall construction, the City of Baltimore, engineer, general contractor, and geotechnical contractor collaborated and worked seven days per week until the residents were able to return to their homes.


The emergency response, design, construction and collaboration required by the team working on the project will be presented.

Presentation Notes

Foamed glass aggregates were originally produced in Scandinavia during the early 1990s for use as a thermal barrier in road construction. Due to their low unit weight (8-15pcf) and high frictional properties, their applications have grown throughout the civil engineering market. Today foamed glass aggregates are used as lightweight fill on highways, bridge abutments, retaining walls, and green roofs. Other applications include backfill of foundations for drainage, insulation (to prevent frost heave), and reduction of lateral loads.


The presentation will review the development, manufacturing, applications current testing and case studies for foamed glass aggregates.


Speaker Biography

Archie Filshill, Ph.D., has over 25 years of experience in geotechnical markets, focused on design/build and value engineering. His work includes in markets for solid waste and industrial landfills, soft soil stabilization, coal ash, shale gas development, flexible solar for landfill closures, sediment remediation, reinforced earth structures and lightweight fill.


Dr. Filshill is adjunct professor at Temple University's Graduate Engineering School. He is Vice Chair of the Delaware Valley Geo-Institute, member of the Geosynthetic Institute and International Geosynthetic Society, and owner and manager of AeroAggregates.


Dr. Filshill earned his undergraduate degree in electrical engineering at Temple University and a master's and Ph.D. in civil engineering at Drexel University.
